Polymorphisms in ADAM33 are associated with allergic rhinitis due to Japanese cedar pollen

BACKGROUND: A recent report provided evidence that a disintegrin and metalloprotease domain 33 (ADAM33), a member of the ADAM family, is a novel susceptibility gene in asthma linked to bronchial hyper-responsiveness. However, there has been no investigation of the genetic role of ADAM33 variants in nasal allergy. OBJECTIVE: The purpose of this study was to test the association between ADAM33 polymorphisms and Japanese cedar pollinosis (JCPsis), a most common seasonal allergic rhinitis in Japan. METHODS: We conducted a case-control association study among a Japanese population, involving 95 adult individuals with JCPsis and 95 normal healthy controls. A total of 22 single-nucleotide polymorphisms (SNPs) in ADAM33 were genotyped using PCR-based molecular methods. RESULTS: Six SNPs of ADAM33 gene, three in introns (7575G/A, 9073G/A and 12540C/T) and three in the coding region (10918G/C, 12433T/C and 12462C/T), were strongly associated with JCPsis (P = 0.0002-0.022 for absolute allele frequencies) and most of the SNPs were in linkage disequilibrium with each other. A higher frequency of the common alleles of these SNPs was noted for the subjects with JCPsis in comparison with healthy controls. We also identified a haplotype associated with the disease susceptibility. In addition, associations were found between ADAM33 polymorphisms and various cedar pollinosis phenotypes including clinical severity, eosinophil counts in nasal secretion and allergen-specific IgE levels in sera, but not total serum IgE levels. CONCLUSION: These results indicate that polymorphisms in the ADAM33 gene are associated with susceptibility to allergic rhinitis due to Japanese cedar pollen, but the functional relationship still needs clarification.     

善宁治疗急性胰腺炎临床疗效观察

目的:观察人工合成的生长抑素类似物(善宁)治疗急性胰腺炎(AP)的临床疗效.方法:对我院1999～2008年收治的156例AP患者分为治疗组与对照组各78例,对照组采用一般常规治疗方法,治疗组在一般常规治疗的基础上加用善宁0.1 mg,缓慢静脉推注后,继以25μg/h的速度持续静脉滴注,连用7～14天.观察两组腹痛缓解时间;实验室检查:白细胞计数、血淀粉酶、血钙与血糖恢复正常时间,多器官功能障碍(MODS)发生情况,恢复进食的时间.结果:善宁治疗组比对照组明显降低血淀粉酶,减少腹痛缓解时间,降低MODS的发生.结论:善宁能有效改善AP的临床症状,减少并发症.     

社交焦虑障碍患者父母的人格特征和心理健康状况调查

目的探索社交焦虑障碍(SAD)患者父母的人格特征和心理健康状况。方法设研究组(SAD患者的父母)和对照组。入组时按要求进行艾森克人格问卷(EPQ)和症状自评量表(SCL-90)评定。结果SAD患者的父母在EPQ量表测验中的内外向因子标准分低于对照组;SAD患者的父母SCL-90各项因子除强迫和敌对因子,标准分低于对照组。结论SAD患者的父母的人格特征倾向内向,易安静、内省、离群、不喜欢接触人;SAD患者的父母更容易表现出躯体化症状、人际交往的困惑、抑郁、焦虑、恐怖和偏执。

丘脑底核电刺激治疗帕金森病术后程控问题分析

目的 总结丘脑底核电刺激治疗帕金森病术后程控经验，提高术后程控水平，改善疗效。方法 对32例丘脑底核电刺激术后的帕金森病患者进行程控，其中单侧植入者6例，双侧26例；年龄40～73岁，在不同刺激器植入中心接受手术，程控时间术后3周至4年之间。程控前均停药10h以上，程控参数调整主要为刺激电极触点、电压、频率、脉宽四项，程控过程中密切观察病员肌张力和震颤等症状改变以及副反应发生情况，作好详细记录，并分别评估患者程控前后药物“关期”和“开期”症状改善情况，部分行UPDRS评分。结果 31例（97％）患者术后症状得到不同程度改善。刺激电极触点选择中，共29例患者采用单极模式，3例因出现持续、无法耐受的副反应采用双极模式。除1位患者使用循环模式外，其他患者均使用持续刺激模式。刺激电压2．0-4．0V，主要集中于2．8～3-3V，是主要的程控调整参数，电压的高低与病人UPDRS运动评分不具有相关性（P〉0．05）。刺激脉宽60～120μs，刺激频率130～185Hz。药物“关”期，患者UPDRS运动评分，在刺激器打开时，平均18．7分；刺激器关闭时平均47．9分。在刺激器打开情况下，药物“开”期患者症状仍然有进一步缓解．主要表现为步态、全身协调动作方面。合并异动患者6例中，3例适当降低刺激电量，1例提高电压后，异动缓解。结论 丘脑底核电刺激术是有效的帕金森病症状控制手段。准确植入刺激电极是术后获得良好症状控制的前提条件，而术后程控是脑深部刺激器置入术后的关键环节．精确的参数调整能够满意控制病人症状。

Genetic polymorphism of UL144 open reading frame of human cytomegalovirus DNA detected in colon samples from infants with Hirschsprung''''s disease

AIM:To explore the genetic diversities of UL144 open reading frame (ORF) of cytomegalovirus DNA detected in colon tissue from infants with Hirschsprung's disease (HD) by sequencing UL144 DNA in 23 aganglionic colon tissue and 4 urine samples from 25 HD infants. METHODS:Nest PCR was performed for amplification of the UL144 gene. The UL144 gene was analyzed with softwares,such as DNAclub,BioEdit,PROSITE database,and DNAstar. RESULTS:The strains from HD patients were distributed among three genotypes of UL144:group 1A (64%),group 2 (24%),and group 3 (12%). The UL144 genotypes between strains from HD and control group were compared by chi square test (χ2 = 1.870,P = 0.393). Strains from the colon were sporadically distributed in UL144 genotypes. CONCLUSION:There are genetic diversities of UL144 ORF in colon tissue of infants with HD. However,cytomegalovirus UL144 genotypes are not associated with clinical manifestations of HD.
